Document Summary
Consbio 11/11/16 deemed extinct in wild, zoos have maintained populations and been successful in breeding animals reintroductions into natural range appear to have been successful. Number of amphibian species at zoos has been increasing since 1994 result of degrading wild habitats. In situ vs. ex situ conservation in situ: on-site ex situ: off-site. Przewalski horse: rely on protection, management, monitoring rely on zoos, aquariums, botanical gardens, seed banks limited to few, charismatic species. Columbia basin pygmy rabbits breed well in large seminatural enclosures individuals released into the wild. Pva: population viability analysis a study of all the factors that may cause a species to go extinct use a model to calculate the risk of extinction/population viability can capture the essence of what is important. Pva: set of population with lambda below 1 decreasing sensitivity analysis: lambda sensitive to juvenile mortality and droughts (suppressed food supply)
